The band play the shows in England and Scotland as part of a 15-date European tour next spring.
Sigur Rós will showcase the expanded brass and string sections which played on their summer shows, but the players will also feature on brand-new material.
"You are limited to what you can accomplish with the 20-minute changeovers and all other constraints of a festival," said bassist Georg Holm.
"To us, this summer's really been one long warm-up for what's to come."
Tickets go on sale this Friday, September 14 at 9am.
Sigur Rós this year released their sixth studio album Valtari.
The full UK tour dates are as follows:
- March 2 - Glasgow, SECC Hall 3
- March 3 - Manchester, O2 Apollo
- March 5 - Wolverhampton, Civic Hall
- March 7 - London, O2 Academy Brixton
- March 8 - London, O2 Academy Brixton
